Abstract
The utility model discloses a novel waterproofing type aerogenerator is with special low tension cable of antitorque song, it is by power core, the filling layer that blocks water, blocks water and form in antitorque bearing enhancement layer, inner sheath layer, outer antitorque bearing enhancement layer and oversheath layer in, around the band. Power core is provided with three groups, the crowded package inside the filling layer that blocks water, power core comprises conductor and power core insulating layer. This kind of cable temperature resistant, resistant oil, ultraviolet light -resistant, waterproof chloride low smoke and zero halogen rubber form cable sheath layer, make the mechanical properties of cable have very big improvement, do not have poisonous gas discharge simultaneously when the conflagration is met to the cable, and the cable is car free torsion with the wind.
Description
Technical field
This utility model belongs to field of cables, particularly relates to a kind of Novel waterproofing type wind-driven generator anti-twist Special low-voltage cable.
Background technology
Wind energy is a kind of clean reproducible energy, along with day by day increasing the weight of of energy shortage, wind energy and the fossil fuel energy sources being present in nature, will not reduce along with the conversion of itself and utilization as the essential difference of coal, oil, natural gas etc. is embodied in it, be a kind of inexhaustible, nexhaustible energy.
Being uncertain due to the direction of wind-force in nature, the direction of blower fan is also as the change in the direction of wind-force and changes.Wind-power electricity generation electric cable and all electrical controls and communication cable all pass through tower from cabin, until guiding to ground control cabinet.If wind-force direction often changes, cable serious distortion will be caused to further encounter rainwater overcast and rainy simultaneously.This just requires that on the one hand this electricity generation system should possess the defencive function distorting cable and blocking water.It is difficult to accomplish under this working environment.On the other hand must be to consider that cable itself should have certain distortion resistance and water-resisting ability, when cable distorts certain special angle and number of times and runs into rainwater the most at a certain temperature, continuous thousand of times the most up to ten thousand times, cable is maintained to properly functioning, cable conductor does not breaks, and insulation and sheath material the most do not occur cracking and be short-circuited because of rainwater.But, the most also there is no a kind of special cable for wind-driven generator with the anti-twist of excellence and block-water performance.
Utility model content
This patent is for avoiding the weak point existing for above-mentioned prior art, a kind of heatproof, oil resistant, ultraviolet resistance, waterproof chloride low smoke and zero halogen rubber is provided to form the coat layer of power cable, the mechanical performance making cable is greatly improved, releasing without toxic gas when fire met by cable, cable can be with the Novel waterproofing type wind-driven generator anti-twist Special low-voltage cable of windmill FREE TORSION simultaneously.
This utility model takes techniques below scheme to realize: a kind of Novel waterproofing type wind-driven generator anti-twist Special low-voltage cable, it is by power wire core, block water packed layer, block water twining package tape, interior antitorque load-bearing enhancement Layer, inner restrictive coating, outer antitorque load-bearing enhancement Layer and external sheath layer composition, described power wire core is provided with three groups, it is extruded in inside the packed layer that blocks water, described power wire core is made up of conductor and power wire core insulating barrier, one layer of twining package tape that blocks water of the outer wrapping of the described packed layer that blocks water, antitorque load-bearing enhancement Layer in the outer wrapping of the described twining package tape that blocks water a layer, one layer of inner restrictive coating of outer wrapping of described interior antitorque load-bearing enhancement Layer, the outer antitorque load-bearing enhancement Layer of the outer wrapping of described inner restrictive coating one layer, one layer of external sheath layer of outer wrapping of described outer antitorque load-bearing enhancement Layer.
Inside and outside antitorque load-bearing enhancement Layer uses aramid fiber yarn fibrage, and interior external sheath layer is in order to fire-retardant rubber that neoprene is base material.
This utility model has the advantages that heatproof, oil resistant, ultraviolet resistance, waterproof chloride low smoke and zero halogen rubber form the coat layer of power cable in sum, the mechanical performance making cable is greatly improved, releasing without toxic gas when fire met by cable, cable can be with windmill FREE TORSION simultaneously.
Accompanying drawing explanation
Fig. 1 is this utility model cross-sectional structure schematic diagram.
Detailed description of the invention
As shown in Figure 1, a kind of Novel waterproofing type wind-driven generator anti-twist Special low-voltage cable, it is by power wire core 1, block water packed layer 2, block water twining package tape 3, interior antitorque load-bearing enhancement Layer 4, inner restrictive coating 5, outer antitorque load-bearing enhancement Layer 6 and external sheath layer 7 form, described power wire core 1 is provided with three groups, it is extruded in the packed layer 2 that blocks water internal, described power wire core 1 is made up of conductor 11 and power wire core insulating barrier 12, the outer wrapping one layer of the described packed layer 2 that blocks water blocks water twining package tape 3, antitorque load-bearing enhancement Layer 4 in the outer wrapping one layer of the described twining package tape 3 that blocks water, one layer of inner restrictive coating 5 of outer wrapping of described interior antitorque load-bearing enhancement Layer 4, the outer antitorque load-bearing enhancement Layer 6 of the outer wrapping of described inner restrictive coating 5 one layer, one layer of external sheath layer 7 of outer wrapping of described outer antitorque load-bearing enhancement Layer 6.
Being embodied as: inside and outside antitorque load-bearing enhancement Layer uses aramid fiber yarn fibrage, interior external sheath layer is in order to fire-retardant rubber that neoprene is base material.
The conductor 11 of this utility model cable is the 6th class soft copper conductor, use multiply fine copper wire stock strand and multiple strand, and for stock strand and the identical version in strand direction again, performance meets the soft copper conductor of GB/T3956-2008 the 6th class. improve the flexibility of cable and torsion.
Insulating barrier in this utility model is to have high anti-tear and excellent electrical properties EPDM glue material to extrude and form, and the most just increases the mechanical performance of power wire core, which improves the security performance of cable.
Have employed during this utility model stranding block water packing fill and the twining package tape that blocks water wrapped improve cable block water and non-hygroscopic function.Using aramid fiber yarn fibrage load-bearing enhancement Layer outside cable core, inner sheath uses rubber with neoprene as base material to extrude simultaneously to use aramid fiber yarn fiber again to weave load-bearing enhancement Layer and improves the distortion resistance of cable.
This utility model oversheath is to extrude form with heatproof, oil resistant, ultraviolet resistance, the waterproof rubber with neoprene as base material, and mechanical strength is good.
This utility model softness is good, and torsional resistance is good, not only has the characteristics such as oil resistant, heatproof, weather-proof, resistance to irradiation to adapt to different working environments, and possesses the distortion performance of excellence, is adapted as the private cable of wind-driven generator.
The above is this utility model embodiment, therefore all equivalence changes done according to structure, feature and the principle described in this utility model application range or modification, all it is included in this utility model patent claim.
